使用聚合物

Question

I need the exact functionality as it is in this code for 2 buttons but in polymer

我的代码段

就我而言，当前按钮应在页面加载时处于活动状态

 <div id="myDIV">                   
        <button class="currentButton " style="margin: 0px 0px 0px 10px;" on-tap="requestCurrentSetPointsData" >Current</button>

 <button  class="currentButton" style="margin-left:10px;" on-tap="requestSetPointsData" >Recommended</button>
  </div>
